Non-vanishing of \(L\)-functions and their derivatives. (English) Zbl 0745.11033

Murty, V. Kumar

Automorphic forms and analytic number theory, Proc. Conf., Montréal/Can. 1989, 89-113 (1990).

[For the entire collection see Zbl 0728.00008.]
The paper in detail discusses the main result of M. R. Murty and V. K. Murty [Ann. Math., II. Ser. 133, No. 3, 447-475 (1991; see the preceding review)] and its implications for modular elliptic curves \(E/\mathbb{Q}\) and also gives an outline of the proofs. In the last section, the author discusses some heuristics on the order of vanishing of \(L(E,s)\) at \(s=1\) and also analogous questions for Artin \(L\)-functions and Dirichlet \(L\)-functions.
